To all whom it may concern sidinget Grafton,

gheny and State of Be it known that I, Jerri: R. KELLER, a

citizen of the United States of America, rein the county cf Alle- Pennsy'lvenia have invented new and useful lrnproveinentsin in sula ted Rail-Joints, of which the following s a iulL'cleztr, and exact description, referencebeing had to the accompanying drawing the meeting ends of "has particular reference tojomt structures in s which form. 'nsrt of this snecification. r This invention relates to devices for oinrzul sections and F of the insulated type.

I As such a device I aim to provide a con struction which affords direct metallic contact of splice bars with rails, with resultant v 1 Y I l increased strength of 301m; in W inch the in- .s'ulating element or elements are preserved or protected from wear or'destmctiong and in which the splice bars may be formed by rollingend are interchangeable or reversible.

I also aim to provide new and improved details of construc'tiont as will be hereinei'ter more fully described.

I Will now "describe my im'entlcn referring to the accon'ipenying; drawings, so that othersskilled in the art to which it appen t'ains understand and construct the seine; it being nreniised, hcwever, that changes nie-y bein ede in the structure shown "whichfwould me depart from the broad principle of-my invent on.

Refering to Figs. 1, send e the inuhirels 2 and 3 indicate the abuttingfenddoifrail sections to be oined by 'ri 'eans of'sjolice bers 4 which in this particular case are shdwif as a-ngile splice bars. Eachbeif made-upbrn p urel ity of sections one orin'oreof which s provlded with rail engagingupperf-and lower surfaces. As shoWmeech spliceibar 4 .13 composed of sections 5 end. Gtheffmii'er of which has a foot orj'atngle flange eiiteiiding the Whole" length,"or"substentiellythe hole length of the joint,Wl1ile I A the-"section 6 elso contacts with thebasefleinge of the rail and has an upper portion or-head's which engages the underside ofthe rail 5 heed. Both splice section's'fti ind-*6 are formed to interlock inf-such manner-that there is afforded a mutual support-of great strength. Thus the sections has aninner long tudinal recess or 1 channel into which extends a relatively narrower p'orti'on 8 0f the section 6; thg g t ib h present proper and desirableco'ecting beerthe head portion 6 of the "se'ction 6" over hangs the body of thesecti0n 5, being provided with a bearing or thrust retes Disposed between the splice's'ection's e' and 6 is an insulating element 9 that; so extendses from the section 5 an'dto alsoin'siilatethe tension 10 lying insnletord't) beiiigfinterandthe lie-fee, This-enables posed between the foot flan e the former is/efiset, as nt c i to insulate the portion 8 ot-th -seeti'en 6* the employment of aflfulleXtensi0n=" foot' flange and insures proper?insulation and full bearing alue. It also enables; hefflnployin'ent' of a splice he'vinge 'suspendingpr depending truss or flange; as indicated in Fig. l' by the letter a. This depending flin'ge' I ortruss mayfbe ofthelu'sualor sny desired cross-sectional shape,; 'as willilbe -tipparent without necessity of 'specific illustration.

Tightening bolts. 11 secure the-s lice bers 'to the rail; in the usual manner; *R'By 'them not only is the bar section 5- drawn-i home s'o that the bearing faces'12 andjf13 ofthe' heedttnd foot respectively are clamped to position, but they also tie the sections together and clamp the' section 6 to its rail section 3. Anti-spreading washers or pieces ll may be interposed between the portion 8 of the splice bar 6 and the web of the rail, where there would be any tendency to spreading, so that with tightening of the bolts 11 the interlocking portions of the bar will be drawn together. Interposed between the rail ends is an insulating strip 9*, and bolts of one-half of the joint may be provided with suitable insulating sleeves and washers. Thus the bolts that pass through the rail section 3 may be provided with insulating sleeves l5 and 16 to insulate the bolts from the splice bars and rail respectively.

In Fig. i I show my joint as embodied in the straight type, i. 6., one not employing a splice bar of the general angle outline. In this view the splice bars 4 are formed of sections 5" and 6' both of which contact with the rail in a manner similar a; that of the construction of Figs. 1, 2 and 3. These sections 5 and 6 interlock, by means of the recesses 7 and extending portions 8, as in the case of the splice sections 5 and 6. In the absence of a foot flange, the section 5 has an extending portion 4 which is bolted to the section 6 by the bolts 11.; the section 6' having an overhanging head portion 6 and a lower head or base or foot member 6 between which the extension 4* is disposed. Insulation strip 9' is disposed between the interlocking splice bar section in a manner similar to that of positioning the insulation 9 between sections .5 and 6 of the angle splice bar arrangement. However, in the present form of joint, the insulating element 9 is not provided with an extended foot portion 10, as said portion is not necessary in view of the absence of a foot flange on the splice bar.

I do not desire to limit myself to any particular form of bar or type of joint. As shown in Fig. 6, the splice section 6 may be shaped so as to project at the head in the manner indicated at 6 As shown F ig, 4, the joint may be provided with a base support or plate 6 between which and the rails or splicebars may be interposed insulation 9".
